Questions tagged [lan]

LAN, or Local Area Network, is a computer network that connects computers and devices in a limited geographical area such as home, school, computer laboratory or office building. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their usually higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines.

A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, or office building.1 A local area network is contrasted in principle to a wide area network (WAN), which covers a larger geographic distance and may involve leased telecommunication circuits, while the media for LANs are locally managed.

This tag can be used for programming problems that are related to LAN networks or similar.
